We propose to run simulations that will be used to predict the impact of the electron cloud effect on the International Linear COllider (ILC) damping Ring and will be used to asses the feasibility of a ring with a reduced circumference.

Simulations of the electron cloud effect will provide a tool to predict the general features of the electron cloud and provide information for possible cures to its instabilities. The code CMAD and other codes will be used to predict the electron cloud effect on the beam in the ILC damping rings. For the next round of simulations we need to refine our simulations to give a recommendation on a reduced damping ring circumference from 6.4km to 3.2km with $200M that would represent a very important cost reduction on the machine costs. This is an important savings for the ILC project that could contribute to make the future machine a reality.
